What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In order to improve the power and energy of water-jet-guided laser, this paper introduces a double beam water-jet-guided laser (DWJL) technology. Based spatially polarized light combination and temporal phase modulation, two lasers are effectively coupled into a water jet with diameter of 100 μm. The maximum output peak power reaches 100 kW and the maximum pulse energy is 4.63 mJ with an operation frequency range from 1 to 20 kHz. The coupling efficiency is as high as 90.4%. Its efficient energy utilization offers new solutions for precision cutting and processing of thick materials. Ultimately, the machining capability of high-power/high-energy DWJL was demonstrated by cutting through 7075 aluminum alloys of varying thicknesses. The cutting depth reaches 10.61 mm, corresponding to a depth-to-width ratio of the cutting gap exceeds 90:1, and the taper is only approximately 0.23°. There is no heat-affected ablation zone on the processed surface. For deep micro holes processing, a minimum radius is 248.54 μm with a depth-to-diameter ratio of 21:1. As the ongoing development of DWJL technology, this innovation is anticipated to find broader applications in aerospace, automotive manufacturing, and high-end equipment manufacturing in the future.
